    Oscillating bucket, variable mass

    I think that the period of oscillation didn't depend on amplitude or other effects.It only depend on m and k.So that T=2π.\sqrt{\frac{m}{2k}}

    Circular Motion Power: Why Isn't Work Done Equal to Zero?

    I think that: v^{2}=v^{2}_{c}+^{2}_{t} But v_{t}=krt And v_{c}=\frac{k^{2}.r.t^{3}}{3} W=1/2.m.v^{2} P=dW/dt=...

    How far can a 1300nm wave travel in 100ns?

    If this is so,are the problem necessary to know wavelength? because we knowed v=c/1.44
